Would it be possible to add a new icon in the message composer to hide blocks ?
While typing a comment, the user would surround text with
[/spoiler] to hide long paragraphs, quotes or code.
Visitors would just see a clickable [spoiler] button, pressing it would reveal the div, showing the content of the
[spoiler] [/spoiler] tags.
Here is the Discourse Hide Blocks plug-in: https://github.com/looker/discourse-hide-blocks
Note, that this plug-in is different than this kind of spoiler (blur) tag: https://github.com/discourse/discourse-spoiler-alert / https://meta.discourse.org/t/discourse-spoiler-alert/12650
This request is just about adding the possibility to hide long blocks of text, which would be handy in some circumstances.
